Message:

I have ajax that calls a php file called "fetch_quarter_limit.php" from template file.

     $.ajax({



         type: 'POST',

         url: 'fetch_quarter_limit.php',

         data: { 

             leavefrom: from,

             leaveto: to,

             empid: emp

         },

         success: function(data) {

            var quarter_limit = data['myVar'];

            alert(quarter_limit);

         }

     });

In my .php file i have tried to return the session data as an array.
Fetched the required data, stored in session and formed an array.

$_SESSION['quarter_limit_mend'] = $quarterLimit;

$returnVal = array('myVar' => $_SESSION['quarter_limit_mend']);

echo $returnVal;

As shown in above ajax code part, i tried to fetch it, but all i am getting is "undefined" when i output the variable using alert.

Please help.

Ajax code updated, p2 :

Adding dataType is making code not to work.

$.ajax({



         type: 'POST',

         url: 'fetch_quarter_limit.php',

         dataType: 'json',

         data: { 

             leavefrom: from,

             leaveto: to,

             empid: emp

         },

         success: function(data) {

             alert(data);

    

         }

 });

As @Tim mentioned i have added custom json encode function to my .php file.
It returns as expected {"myVar": 2}

echo array_to_json($returnVal);

This is returned from php file.
But not able to access in ajax code.

My Answer:
To access PHP session data inside template files in jQuery code, you can pass the session data as a parameter in your AJAX call to the PHP file. Here's an example:

1. In your template file (e.g. index.php), you can store the session data in a JavaScript variable like this:

html



2. In your jQuery AJAX call, you can pass the session data as a parameter like this:

javascript
$.ajax({
url: 'your_php_file.php',
type: 'POST',
data: {
sessionData: sessionData
},
success: function(response) {
// Handle the response from the PHP file
}
});


3. In your PHP file (your_php_file.php), you can access the session data like this:

php
session_start();

if(isset($_POST['sessionData'])) {
$sessionData = $_POST['sessionData'];

// Use the session data as needed
}


By passing the session data as a parameter in your AJAX call, you can access the PHP session data inside your template files in jQuery code.
